Problems solved by technology

When the display panel is a flexible display panel, due to the long line length of the straight metal leads and the limit of the fracture strain limit they can withstand (the fracture strain limit of the metal itself is about 1%), when the display panel is bent, Metal leads have poor bending resistance and are prone to breakage or disconnection, resulting in abnormal signal transmission

Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0032] figure 1 is a schematic diagram of a display panel in the prior art, refer to figure 1 , the display panel includes a substrate 101 and metal wires 102, and the metal wires 102 are linear. When the display panel is bent along the Z1 direction in the figure, the metal wires 102 are likely to break under the stress, resulting in the failure of normal signal transmission.

[0033] To solve the above problems, this embodiment provides a display panel. figure 2 is a schematic diagram of a display panel in an...

Abstract

The embodiment of the invention discloses a display panel and a display device. The display panel includes a flexible substrate, and metal leads are arranged on the flexible substrate, and the metal leads have a plurality of hollow areas in the extending direction. The embodiment of the invention improves the bending resistance of the metal lead.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular, to a display panel and a display device. Background technique [0002] With the development of display technology, the display effect of display products has been continuously improved, so that the application of display products has become more and more extensive. [0003] In the prior art, the metal leads in the non-display area of ​​the display panel are mostly linear. When the display panel is a flexible display panel, due to the long line length of the straight metal leads and the limit of the fracture strain limit they can withstand (the fracture strain limit of the metal itself is about 1%), when the display panel is bent, Metal leads have poor bending resistance and are prone to breakage or disconnection, resulting in abnormal signal transmission. Contents of the invention [0004] The invention provides a display panel and a display device to improve th...
